OptoSigma's AND-15C-001 is a high-quality Neutral Density Filter, designed to minimize the effects of light intensity in optical systems. This unmounted filter, with a diameter of 15 mm, is specifically designed for use in the visible light spectrum, between 400-700nm.
The filter is made from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability. It features a thickness of 2mm, providing robustness and stability in its placement within optical systems. The filter's coating, Opt AND-001, is applied to both the front and back surfaces, enhancing its light absorption capabilities and ensuring a consistent neutral density across the visible spectrum.
The filter's shape is that of a thin lens, which is beneficial in reducing unwanted optical aberrations and improving the overall performance of the optical system. The filter is currently in stock and available for purchase through the OptoSigma website, as indicated by its valid weblink status.
